“…The percentage of settlement that occurs in the proposed reinforcement alternatives compared to the unreinforced embankment is also much smaller; the geotextile 2 alternative can reduce the settlement by 11.48% during the construction lifetime plan. This result is in line with research from(Surachmat et al, 2019). The encapsulated stone column can reduce the settlement by 70.15% over the life of the construction plan (Table9).Table 9.…”

“…(Gouw, 2018). The use of geosynthetics in embankments on soft soils can also reduce the settlement of the subgrade by an average of 7.633% in the short term and 4.113% in the long term when compared to the embankment which not using any reinforcement (Surachmat et al, 2019). Meanwhile, if geosynthetics are added with PVD installation, the number of geotextiles used for embankment reinforcement will be reduced and can save geotextile costs.…”

One of the road damages caused by problematic soil is found on the Calang -Simpang Peut Road Section. Soil testing data shows that soft soil exists at a depth of zero meters, up to five meters. The damage is being repaired using a Modified Chicken Claw (CAM) system. The CAM system is built on a road embankment. Using the CAM on the top of the road embankment has a settlement problem that will cause nonuniform settlement. This study reviews three alternatives that have been proven effective and efficient in fixing road embankment failures on problematic soils. These alternatives are geosynthetic reinforcement, geosynthetic reinforcement with prefabricated vertical drain (PVD), and encapsulated stone columns. This research will analyze the three alternatives based on their efficiency and effectiveness in treating the damage. The results of the calculation analysis show that the geosynthetic-reinforced embankment is the most effective alternative design. The alternative can also reduce the execution time by 42% and cost by 43% compared to the CAM system. However, a subgrade improvement alternative with encapsulated stone columns increases the execution time by 20% and cost by 25% compared to the CAM system, and using a PVD alternative is not recommended to repair the road embankment on this road section.

Kata kunci: daya dukung, geotextile, kuat tarik maksimum (Tult), prefabricated vertical drain (PVD) AbstrakKebutuhan perkuatan geotextile dipengaruhi oleh kondisi tanah dasar itu sendiri. Perbedaan kondisi tanah dasar ketika dengan pemasangan PVD (Prefabricated Vertical Drain) dan tanpa pemasangan PVD terletak pada daya dukungnya. Daya dukung tanah dasar dengan pemasangan PVD lebih tinggi daripada tanpa pemasangan PVD, hal tersebut dikarenakan kenaikan harga Cu sebagai akibat pemampatan konsolidasi sehingga mempengaruhi jumlah kebutuhan perkuatan geotextile. Pada geotextile dengan Tult yang sama, kebutuhan jumlah perkuatan geotextile dengan pemasangan PVD lebih sedikit daripada tanpa pemasangan PVD, sedangkan pada geotextile dengan Tult yang bervariasi terdapat batasan untuk kondisi tanpa pemasangan PVD. Pada kondisi tanpa pemasangan PVD, semakin tinggi timbunan maka Tult geotextile yang digunakan semakin tinggi, sedangkan untuk kondisi dengan pemasangan PVD, Tult geotextile yang digunakan untuk semua variasi tinggi timbunan dalam penelitian ini minimal 50 kN.

Subsidence is a change in the composition of the soil and small spaces in the soil. The method that can be chosen to reduce the rate of decline that occurs on the road is preloading and adding geotextiles. The purpose of this study was to analyze the settlement that occurred in the embankment soil before and after the geotextile was applied. The research location is on Jalan Tolango-Bulontio STA. 47+600 Wubudu Village, East Sumalata District, North Gorontalo Regency. The primary data used is the characteristics of the embankment soil, while the secondary data is in the form of plan drawings, N-SPT values, and geotextile characteristics. Land subsidence analysis was carried out by modeling in two dimensions using the finite element method with the help of the Plaxis 2d v20 application. Structural modeling using plane strain model. The results showed that the settlement of the embankment using geotextiles that the settlement of the embankment soil at point A (shoulder) was 33 mm <65 mm, while the settlement of the embankment without geotextile was greatest at point A (shoulder) of 33 mm. mm < 65 m (allowable descent). The settlement value of the embankment without geotextiles and the use of geotextiles did not have a significant difference because the geotextiles used only functioned as filtration, not as reinforcement
